Hello, i dont have any executable file in my game lol

Game downloads (although only 0 bytes) and shows up in my library. But when launching it says it's missing files. Obviously. There are more than a 100 Linux supported titles in my library. Never came cross of this thing before. Again: Downloading and installing gives no errors. It just goes very fast because it's downloading and installing 0 bytes! Instead of the 1 GB + the game actually is. Please fix the downloading for Linux. Thanks! ...

Is there any chance to have controller or maybe Steam Deck support??
